Fig'. 91s a pfrspective View of a connection member. 6* l Referring to the drawings, No. 1 represents the bowl of a water-closet orthe like, with which the seat 2 is associated. rllheseat 2 is of general U- shape facing forwardly, `the* side members 3 converging inwardly as illustrated. The rearror crossV member 4 andthe side members 3 arechambered or hollow, being preferablyvformed of aluminum castings or of'sheet metal which maybe enameled or nished as desired. v

The side members 3 are divided into separate supply roll and take-up or winding roll compartments 5r and 6 by vertical Walls 7 of substantiallyy inverted L-shape, which are disposedlongitudinally of the side members and aresecured to the tops thereof bya, welding at 8. The lower ends of the walls 'l are provided with offset portions 9 which` are adapted to coact with similar offset portions providedon thev spaced retaining membersul() of thedetachable bottom sections 1-1. Take-up and supplyspools 12 and 1 3 are rotatably Vdisposed in the compartments 6 .and 5 respectively. The side members Vare providedY with opposed longitudinal slots 14 and 15 through which the webs or sheets extendfromthe supply and takeup rolls over the tops of the side members.

The bowl 1 is provided with spaced supporting posts 16 which carry a forwardly facing SuDDOrting yoke or member 1'7'of substantially U-shape,V having alined inwardly extending journals 18 which coact with bearing 19 Yprovided thereforin the sides of the rear or cross member 4V.V

segmental gears or-racks 20.are xed to the inner ends of the journals 18 and mesh with beveled gears 21 provided on the gear wheel 22 which is rotatably carried by the verticalv spindle` 23. The spindles 23 are tubular and are secured in place by means of screws 24 which extend lthrough thetop and bottom walls of the rear seat member 4. The gear wheels 22 mesh with beveled pinions 26 carried by the shafts 27. The arrangement of the gear wheels 22 and their meshing gears issuch that when the gear `wheels are rotated, the seat is swung about the journalsV 18 and also the pinions 26 are rotated so as to actuate the take-up rolls.

The gear'wheels 22 are Aautomatically rotated by .means of a tension spring 28 which connects them and is disposed within thev hollow rear member f1, as illustrated.r Thegear wheels 22 are provided with upwardly extending studs 29 which ber 43 and extends forwardly into the rotatably carries sleeves 30, having annular peripheral grooves 31 constituting seats for the ends of the tension spring 28. The tension spring 23 is adapted to rotate the gear wheels toward each other at all times so that when the seat is released the spring causes the gear wheels 22 to rotate and drive the racks so as to swing the seat upwardly about the journals 18. The arrangement is such that the spring 28'exerts a greater force when the seat is in a horizontal position than when it is in its raised or vertical position. This is due to the fact that as the spring 28 moves the studsv 29 together in raising the seat, it weakens itself in the manner of tension springs.

The beveled gears 26 drive the take-up rolls through a driving clutch 32 and a ratchet device 33. The driving clutch is adapted to provide a driving connection'between the pinions 27 and the take-up spools 12 when the seat is raised by the springA 28 whereby the paper' covering is fed or renewed on the side members and to permit the seat to be lowered without connection between theV spindles 27 and the take-up spools 12. The driving clutches 32 preferably consist of substantially rectangular driving clutch members 34 which areprovided with spring seats or recesses 35 and opposed grooves 36. The driving clutch member- 34 is surrounded by a drum-like driving clutch member' 37 Pawls 38'are disposed between the clutch member 34`and the drum 37. The pawls 38 are provided with knuckles 39 which are disposed in the grooves 36 and spring recesses 40 alined with the spring recesses35. vCompression springs 41 are carried by the recesses 35 and 40 for forcing the pawls into engagement with the inner periphery of the drum 37. The faces of the pawls which contact with the drum are serratedor toothed for facilitating their engagement A, clutch member 41 to rotate free of the drum 37.r

with the drum. When the clutch member 34 is turned in a clock-wise direction, as illustratedby Fig. 7, the pawls pivot in the grooves 36 against the force of the springs 41 which permits the However, when the clutch member 34 is rotated in a counter clockwise direction, as indicatedv by Fig. 7, the pawls engage the drum 37 and cause it to rotate with the driving member.

The drum 36 is supportingly embraced by a sleeve 42 which is fixed relative to the seat'and extends forwardly beyond the drum 37. This sleeve 42 constitutes a stationary supporting element which is associated with the holding ratchet 33. The holding ratchet consists of the member 43 which is integrally connected to the driven member 37 of the clutch and which is provided with detents 44 and springs 45 which are similar in construction and operation to those described above Vin connection with the drivingclutch. Their operation is such that when the drum 37 is positively driven, they detents 44 slip freely within the sleeve 42. When, however, it is adapted to rotate the clutch member 43 in a reverse direction, then the detents 44 lock in engagement l with the sleeve 42. This arrangement positively obviates the possibility of the reverse rotation of the take-up, spools 12 and prevents the Vdevice lfrom operating in a reverse direction.

The sleeve 42 is provided with rearwardly extending upper and lower portions 46 and 47 whichv nissan@l take-up roll compartment 6i or engagement with the takeup spool 12. The latter is provided with a cupshaped connecting member 49 of fiber or the like, having a non-circular hole l5() which registers with a non-circular part on the journal 48, as clearly illustrated by Fig. 4. While I prefer to use a hexagonal journal and hole for the cups 49, it will be appreciated that any noncircular or polygonal connection may be made.

The pinions 27 and the journals 43 are rotatably supported by spaced vertical members 51 and 52 'which are in turn carried by the fixed sleeve 42.

V The spools are rotatably carried between supporting discs 53 and 54. The inner supporting discs 53 of the take-up spoolsl2 are urged outwardly into engagement therewith by means of compression springs 55 disposed between the walls 56 and said discs. The supply spools 13 are held in position between the supporting discs 53 and 54 by means of inner journals 57 carried by the discs 53 whichV are disposed in cup-shaped bearing members 53 in which-are housed compression springs 59 for urging the supporting discs 53 outwardly into engagement with the supply spools 13. The cup-like bearings 58 are integral with theV walls 56 whichare welded to the interior of the side members at'60 and 61.

The supply spool 13 is, of course, wound with 105 a sheet or web 62 of suitable material such as paper to form the supply roll 63. As pointed out above, the sheet V62 passes from the supply roll 63 through the opening- 14 over the top of the side member 3, thence downwardly through 110 the opening 15 and on to the take-up spool 12 to constitute a take-up roll 64. The take-up and supply rolls are readily renewable by merely removing the bottom section 11 which is detachably secured to the wall 7 as described above;

' In operation, whenthe seat is released from a horizontal position, it is raised by the force of the tension spring 23, as described above, which at the same time actuates the take-up spool 12 through the driving clutch 32 to renew the paper covering on the top of the side members 3. When the seat is again lowered, the clutch 32 disconnects the take-up rolls from the pinions 27 in the manner described above.

-From the above description, it will be apparent to those skilled in the art that the'device is relatively simple in construction and highly eiiicient in operation. Very few working parts are required, yet the device works positively and accurately to accomplish the desired purpose.

I have not attempted to illustrate or describe various modincations and adaptations which I contemplate', as it is believed that this disclosure will enable those skilled in the art to make such modiications and adaptations as may be desired. 135
